Exemplos

O exemplo de código a seguir preenche a comboInstalledPrinters caixa de combinação com as impressoras instaladas e também define a impressora para imprimir, usando a PrinterName propriedade , quando a seleção é alterada. A PopulateInstalledPrintersCombo rotina é chamada quando o formulário está sendo inicializado. O exemplo requer que exista uma PrintDocument variável chamada printDoc e que a caixa de combinação específica exista.

private:
   void PopulateInstalledPrintersCombo()
   {
      // Add list of installed printers found to the combo box.
      // The pkInstalledPrinters String will be used to provide the display String.
      String^ pkInstalledPrinters;
      for ( int i = 0; i < PrinterSettings::InstalledPrinters->Count; i++ )
      {
         pkInstalledPrinters = PrinterSettings::InstalledPrinters[ i ];
         comboInstalledPrinters->Items->Add( pkInstalledPrinters );
      }
   }

   void comboInstalledPrinters_SelectionChanged( Object^ sender, System::EventArgs^ e )
   {
      // Set the printer to a printer in the combo box when the selection changes.
      if ( comboInstalledPrinters->SelectedIndex != -1 )
      {
         // The combo box's Text property returns the selected item's text, which is the printer name.
         printDoc->PrinterSettings->PrinterName = comboInstalledPrinters->Text;
      }
   }
private void PopulateInstalledPrintersCombo()

    // Add list of installed printers found to the combo box.
    // The pkInstalledPrinters string will be used to provide the display string.
    String pkInstalledPrinters;
    for (int i = 0; i < PrinterSettings.InstalledPrinters.Count; i++){
        pkInstalledPrinters = PrinterSettings.InstalledPrinters[i];
        comboInstalledPrinters.Items.Add(pkInstalledPrinters);
    }
}

private void comboInstalledPrinters_SelectionChanged(object sender, System.EventArgs e)

    // Set the printer to a printer in the combo box when the selection changes.

    if (comboInstalledPrinters.SelectedIndex != -1) 
    {
        // The combo box's Text property returns the selected item's text, which is the printer name.
        printDoc.PrinterSettings.PrinterName= comboInstalledPrinters.Text;
    }
}
Private Sub PopulateInstalledPrintersCombo()
    ' Add list of installed printers found to the combo box.
    ' The pkInstalledPrinters string will be used to provide the display string.
    Dim i as Integer
    Dim pkInstalledPrinters As String

    For i = 0 to PrinterSettings.InstalledPrinters.Count - 1
        pkInstalledPrinters = PrinterSettings.InstalledPrinters.Item(i)
        comboInstalledPrinters.Items.Add(pkInstalledPrinters)
    Next
End Sub

Private Sub comboInstalledPrinters_SelectionChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles comboInstalledPrinters.SelectedIndexChanged
    ' Set the printer to a printer in the combo box when the selection changes.

    If comboInstalledPrinters.SelectedIndex <> -1 Then
        ' The combo box's Text property returns the selected item's text, which is the printer name.
        printDoc.PrinterSettings.PrinterName = comboInstalledPrinters.Text
    End If
